METAL-WORKING TOOL.

To all whom it may concern:

Be it known that 1, KING D. MCQUEEN, a citizen of the United States,residing at Arlington. in the county of Hudson and State of New Jersey,have invented certain new and useful Improvements in Metal- VVorkingTools, of which the following is a specification. v

This invention comprehends certain new and useful improvements in metalworking tools and has for its primaryobject to pro vide a tool of thischaracter which will be of simple construction and operation as well ashighly efficient in use.

Another object is to provide a device of this character which will beconstructed in such manner that it may be readily employed for formingapertures at opposite sides of an opening in metal.

A still further object of this invention is to provide a tool of thischaracter which will be constructed in such manner that the metalpenetrating members will be located upon opposite sides of and below thepivot point in the handles by which said penetrating members arecarried.

This invention has for a still further object to generally improve toolsof this character and construct the same in such man ner that the metalpenetrating members may be readily forced through the material andagainstthe handle members positiond upon the opposite side of thematerial and serving to clamp the same and prevent said material frombending during the operation of the tool.

WVith these and other objects in view as will become more apparent asthe description proceeds, the invention consists in certain novelfeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had tothe following description and accompanying drawings, in which- Figure 1is an elevational view of the complete device, showing the preferredform, Fig. 2 is a transverse detail section on the line 2-2 of Fig. 1,Fig. 3 is a longitudinal section on the line 3-3 of Fig. 1, Fig. 4: is afragmentary elevation of a modified form of the tool, Fig. 5 is asimilar view of a still further modified form, Fig. 6 is a bot-Specification of Letters Patent.

tom plan of the form shown in Fig. 4, Fig. 7 is a bottom plan of theform in Fig. 5, Fig. 8 is an elevation of one of the form of tools shownin Fig. 41, removed, and Fig. 9 is an elevation of the semi-sphericalhead of one of the handles, looking at the inner face thereof.

Referring in detail to the drawings by numerals, 1 designates a pair ofhandles having enlarged and flattened crossed forward ends 2 terminatingin substantially semi-spherical heads 3 having their fiat sides engagedagainst one another and pivotally connected by means of the pivot member4: engaged through said heads and forming a pivot point upon which thehandles 1 may be rotated, during the operation of the dev1ce.

Projecting from one side of each head 3 and outwardly of the pivotmember 1 is an arm 5 having a material penetrating blade 6 positionedalong the radially directed edge thereof and the arms 5 preferablyextend in opposite directions, whereby when the heads 3 are engagedthrough an opening in a sheet of metal or the like and the deviceoperated to draw the handles 1 toward one another, said cutting blades 6will be forced through the material at opposite sides of the opening andform radially directed slots extending from the opening, atdiametrically opposite points, the cutting blades 6 and the material cutout by the same being forced against the top walls 7 of the for wardright angled ends of the enlarged portions 2 of the handles 1 directlyagainst the outer face of the material through theopening of which theheads 3 are engaged. It will be understood that slots 8 are preferablyformed in the forward endsof the portions 2, as shown in Fig. 1, toreceive the blades 6 and the material cut out by the same. Each blade 6tapers toward its outer end and has its cutting portion extended at aright angle with respect to the remainder of the opposite edge of theblade, as will be readily understood by referring to the drawings. Eachblade is also removably positioned in. the recess 13 formed in the innerface of the head 3 by which it is carried, and is provided with a recessof concaved inner end 16 to avoid the pivot member 4. It will thereforebe seen that each blade 6 is securely. positioned in the head by whichit is carried with the working end thereof projecting beyond the headand resting upon the arm 5 of said head, and outward movement of theblade will be prevented. The blade may be readily removed, however, fromits head, after the pivot member 4 has been removed.

It Will bereadily seen that by having the material penetrating blades 6below or outwardly of the pivot member 4 When penetrating the material,said pivot member is relieved of a large amount of the strain and morepressure may be exerted upon the blades, thereby causing the blades tomore readily cut or sever the material and eliminate danger of theblades tearing the material. This will greatly increase the ethcioncy ofthe device and permit the tool to be readily and easily operated, and itwill be readily seen by all familiar with devices of this character,that this tool is especially adapted for use by electricians whensetting up electric signs and. forming openings to opposite sides of alarger opening in a. sheet of metal. forming a part of the *asing of thesign, to extend the screws through said casing.

In F d, I have shown a modified form of the device, in which ispositioned on the arm 5 projecting from the head 3, a punch (3projecting radially from the free end of said arm 5, and having anupstanding cylindrical punch proper 6 formed on its extremity topenetrate the material and enter the socket 8 in the opposite rightangled. end 7 of the other handle and thereby produce a circular openingin the material to opposite sides of the large opening through which theheads 3 are engaged.

l't'will be understood that each punch 6 is mounted in one of the heads3 in a manner similar to that described in the preferred form of thedevice, and owing to the form of the punches 6, the small cir-- cularopening produced by the same in the material will be spaced from thelarge open mg. p

In the further modified form shown in Fig. 5, each head 3* has an arm 5projecting therefrom and the heads 3 are connccted by the pivot member46 the same as in the other two forms of the device. Positioned in arecess 13 in each head 3 is an outwardly tapering and tangentiallydirected punch 6 having the usual curved or concaved inner end 16 forengagement a ainst the pivot member 4:. It Will be understood that thispunch is of substantially the same form as the above described punchWith the exception that it is provided with a sharp pointed upstandingpunch proper 6'. This sharp pointed punch proper 16, after penetratingthe material, enters a conical socket 8"in the right angled end]? of theopposite handle, against which end is pressed the material around theedge of the opening formed by the said opening. d it Will be readilyunderstood from the foregoing, that in all of the forms of this gages inslots or sockets formed in the nardly oi? the head formed thereon. Itwill also be seen'that the material penetra'ting members may be readilyremoved or ther be understood that the working parts of this device maybe reversed and the material penetrating members carried by the enlargedends of the handles, if desired. Further, many other minor changes inthe details of construction and arrangement of parts may be made Withinthe scope of the appended. claims without departing from the spirit ofthe invention or sacrificing any of the advantages thereof.

lVhat is claimed is 1. A device oi the class described comprisingcrossed members having semi-spherical heads formed at their forward endswith enlarged portions inwardly of said heads, a pivot member engagedthrough said heads, said enlarged portionshaving reformed therein, anarm carriedby each head with a material penetrating member projectingtherefrom and adapted for engagement in the recess of the opposite head.

2. A device of the class prising crossed members having heads formed attheir outer encs for engagement through. an opening in a sheet ofmaterial, a pivot member engaged through said head, said. crossedmembers having enlarged portions to opposite sides of the heads withrecesses formed therein, and material pone-- described com- Wardly ofthe pivot point and to the oppo-' site sides thereof and adapted forengagement in the recesses formed in the enlarged portions of saidmembers.
